Highly textured polycrystalline fibres of monoclinic P2₁/c Nd₂SiO₅ and hexagonal P6₃/m Nd_9.33(SiO₄)₆O₂ phases were obtained by Laser Floating Zone in air from stoichiometric mixtures of Nd₂O₃ and SiO₂ changing the pulling rate from 10 to 400 mm/h. Distribution of phases barely varied due to the incongruent melt of the Nd₂O₃:SiO₂ system, resulting in fibres adequate for microwave devices owing to the dielectric character of the Nd₂SiO₅ phase. Raman analysis was performed in this material for the first time.

空气中激光浮区对Nd ₂ O ₃：SiO ₂体系的处理

通过在空气中从空气中改变Nd ₂ O ₃和SiO _2的化学计量比的混合物，通过激光浮区获得了单斜晶P2 ₁ / c Nd ₂ SiO ₅和六角形P6 ₃ / m Nd _9.33（SiO ₄）₆ O ₂相的高织构多晶纤维。牵引速度从10到400 mm / h。由于Nd ₂ O ₃：SiO ₂体系的熔融不完全，相的分布几乎没有变化，由于Nd ₂ SiO ₅的介电特性，导致了足以用作微波设备的纤维相。首次在这种材料中进行拉曼分析。
